It's 2026 and Proton Mail still doesn't have a simple text wrap or line-width setting in the web composer. I'm writing on a large monitor, and when I compose emails, the text stretches across my entire screen. It's hard to read and makes editing paragraphs frustrating.

This is not an advanced feature request. Line wrapping or the ability to constrain the compose area width is fundamental functionality that should exist in literally any email client. Gmail, Outlook, Apple Mail — all of them handle this without complaint.

I understand Rich Text mode wraps to the window edge, but that doesn't solve the problem when the window itself is wide. And Plain Text mode doesn't wrap at all. There's no setting to define a maximum character width for composing, which would let me write comfortably without constantly resizing windows.

I shouldn't need to manually resize the composer every time I write an email just to get readable line lengths. A simple toggle or slider in the Composing settings for "line width" or "soft wrap margin" would fix this.

Please prioritize adding this. It's a basic quality-of-life improvement that your competitors already offer years ago.
